speoficatioa of Lettere. Patent.: 'Patented Nov. 2, 1920 Application filed October 26, 1918. Serial No. 259,838.

To all 'whom et may concern Be it known that I, HENRY G. LYKKEN, a citizen of the United States,f residing at Minneapolis, in the county of Hennepin and State of hllinnesota, have invented a new and useful lllmergencyffire, of which the following is a specification.

This invention has referenceto emergency tires, and is intended more particularly for use in an automobile as` an emergency tire in connection with the cleneher type of wheels such as are used upon the Ford and other makes of autoniobiles.

vThe repair and replacing of elencher tires on the road is a laborious andl dlsagreeable task7 of dii'licult accomplishnient, taking 4con-` siderable time and it is frequently a dirty job. In order to avoid these disagreeable conditions, it has been proposed to provide demountahle tires which may be removed and replaced by the manipulation of a` few bolts. For autoniohlles equipped, as is the Ford automohile., with front and rear wheels.

of different sizes, it is necessary to 'replace the standard eqiiipnientwith an lentirely new:`

spe'ctive of the fact that theV wheels and rinia are of different diameters.

rlhe invention coinprises a rim with a t'ire thereon, either solid or cushion or pneumatic, as desired, which rim' will fit either the front or rear wheels of the automobile, and filling andv holding means are provided for properly spacing and 'seou'ring the rim;

with the tire thereon, with respect to the:

clencher rim alreadl;T in place on thei'wheel. lVith such an equipment, all that ls necessary 'is to remove the damaged tire and slipV the emergency tire onto therim, either the front or rear rim, as the oase may be, and,

fasten it in place witha suitable number of bolts, say four or iiy'e'loolts;`

1With a pneumatically equipped vehicle the `remergency tire is` 1intended only foriv emergency purp'oses, to `loe replaced by the Fig. 8.

original tire as soon as may be. For trucks and other vehicles employing solid tires, the emergency rim and tire, ifV a. solid tire be used, may remain on the vehicle an indefinitely long time.

P The inven'tion will he best understood Irom a consideration of the following detailed description taken in connection with the aecompanying drawings forming a part of this speoification, with the understanding, however, that the invention is not confined to any striot conforniity with the showing in the drawings, but lmay be changed and modir` fied so long as such changes or modifications mark no material departure from the salient features of the inrention as expressed infthee claims.

In the drawings, i

Fig. 8 is a view similar to Fig-.3 but showing still another form of the invention; and

Fig. 9 is a section on the line 9-9 of Referring to the Vdrawings,there is shown in Fig. l a wheel l and in Fig. 2 another wheel 2, the wheel l. representing one of the rear wheels of a F ord automobile and the wheel 2 representing one of the front wheels ofa Forflautoniohile, the front and rear wheels difiering in' diameter by about one inch, and-the standard equipment of tires also difiering in diameter correspondingly. The wheels .are provided with the clencher type of rims indicated at 3 and' et, respec-l tively, diil'ering in diameter in like manner to the bodies of the wheels.

There is also provided another rim 5 which "may be of channel form, and mounti' the overhangof a pneumatic tire. k

blocks 7 and 14 similarly overhang the rlm. 3 or a, as the case 'may be, while that portionl ed in such rim 5 is a tire 6. ln Figs. 3 and 11 the rim 5 is a plain channel with parallel sides and the tire 6 is a solid rubber tire of 7suitable type permanently mounted in the rim 5. The inner diameter of the rim 5 is considerably greater than the outer diameter of the rim 3, whereby to accommodate certain structures to be described. But the external diameter of the tire 6 may correspond to the external diameter of a standard pneumatic tire such as is'us'ed on the Ford automobile; f

At-suitableintervals about the inner periphery of the rim 5 wedge blocks 7 are made fast in any suitable manner, as by rivets 8, the taper of the wedge blocks 7 extending fromi side to side of the rim 5. Each wedge block 7 is providedat the thick end with an insetlip 9 extended toward the aXisV of the rim 5, thereby produ'clng a reces's or v cut-'out 10. The lip 9 has a perforation 11 through it for a screw 12 having a head 13 entering the recess 10 so as to be fiush, or nearly so, with the corresponding side face of the rimi. V

There are also provided as many wedge blocks 1-1 as there are blocks 7, and in each block let there is produced a recess 10CL to receive the Vlip 9. The blocks 7 and 14 are elongated circumferentially of the rim 5 and have a curvature conforming thereto.

ln the particular showing of the drawings theV tire V6 with the rim 5 is; somewhat wider than the clenched rim 3 or el so as to overhang it at the sides, in like manner to The of each-block 14: toward the center of the wh'eel is of reduced width lto form a tongue or projection 15 of a width to snugly lit between the side flanges of the rimv 3 or 41, as the caseflmay be.4 Each block 141 has a suitably tapped perforation 10 to receive the screw 12 or in the case that bolts be used the perforation 10may`not be tapped.

Then a pnncture or blow-out occurs in the ordinary pneumatic tire equipment, the damaged tire is removed in the usual manner and the emergency tire may replace it. To do this, a suitable number of blocks 111 are placed in the rim 3 or fl, as the case may be, and properly spaced, the blocks lit-ting snugly between the side of therim so that they will retain the positions in which they are placed. Now, the emergency rim is so positioned with respect to the blocks 111 that the emergenciT rim maybe moved onto the outer beveled or wedge surfaces of the blocks 14l from the outer face of the wheel. The arrangement is such that this movement may be accomplished with ease, it being understood, of course, that the wheel is jacked up, and the beveled faces of the blocks 7 and 141 will contact just before the emergency rim reaches its final position. Thenv the screws or bolts 12 are inserted and turned tight, thereby en'gaging the lips 9, thus forcing the blocks 7 into tight engagement with the blocks 14 and centering and holding the emergency rim and tire in place. t I

c i The whole Operation may be performed in a very few minutes with the labor of forcing a tire onto a clencher rim entirelyeliminated, andthe greater portion offthe .dirty work accompanying the remova'l, repair and replacing of pneumatic tireson the road,

avoided. A solid tire may be very satisfacrim, and such length will depend upon the number of pairs of'blocks used. Thescrews and contacting'wedge surfaces permit a suficiently tight it and sufficient frictional engagement to avoid all creeping. Moreover, Vthe' emergency rim is looked to the blocks 11'byl the lips 9 so that .the blocks must' maintain' their 'relative positions at all times. The blocks may be made of wood or other material, including metal, and by making the blocks '141 of different radial thicknesses and'providing two Vsets of blocks, one for the hfront wheels and the other for therear wheels, the emergency rim may be `secured ito eitherthe front or rear wheels indifllerently. n

In the arrangement'shown in Figs. 3, l, and 5,1a-screw12 is employed 'to hold the two blocks of each pair together. Inl thel structure shown in Figs. 6 and 7, the block leihas a nut 16a set into it, the nut being provided withfside-i'ianges 17 and a tongue i 18 seatmg the nut in the tongue .portion 15.V

i of the block so that it will retain its place at all times. With the structure shown in Figs. 6 and 7, the block 14 may be very conveniently made of wood with the nutV 16a of metal. I 'H In ing; e the 101001: :f .ismpnced :by gmother iblock 7fl, suitablyfjournaledion the. i

' 7 and lfl which may be' generally the same as those shown in Figs. 3 and 4:, but instead of providing a lscrew or bolt for securing the blocks together, the lip 9 and block 14 have matching passag'es 19 therethrough traversed by a iiat key- 20 with a head 21 at one end for engaging the lip 9, while the other end 22 of the key is of sufficient length and the key is made'of suitable materials permitting the end 22 to be turned over against the corresponding portion of the block 14, thereby locking the parts in place. The turning over of the key and the drawing of the wedge portion of the blocks into tight engagement may be accomplislied by the use of a hammer, or other like tool, and 'an anvil of any suitable character. i

lt will be understood thatthe showing is but indicative of many forms which the invention may assuine, the invention being intended to provide an emergency tire and rim ready for application in case of need, requiring, in types of automobiles represented by the Ford automobile, but a single einergency tire without any change whatever in the standard equipment of the vehicle.

Ordinarily the tire or tread of the einergency rim is of the solid type, but, of course, it is evident that a cushion or pneumatic tread may be substituted for a solid tread. lVhere the standard equipment of the vehicle is made by solid tires, the emergency equipment may follow the type of solid tire employed and, in such case, the early exchange of a pneumatic tire for the solid tire is not necessary since the emergency tire may be retained as long as desirable.

The wedge blocks 7 are, in effect, permanent parts of the emergency'rim, while the wedge blocks 14- are separate members to be placed in the standard rim when it is necessary to apply the emergency tire. .The tightening of the emergency rim on the standard rim is accomplished by force applied parallel to the axis of the rotation of the Wheel but acting perpendicularly to such axis to wedge the emergency rim in place and hold it against creeping circumferentially of thevwheel and displacement side- Wise of the wlie'el.
